Benjamin just finished brewing a cup of coffee. Which of the following is an example of thermal energy in this scenario?

• The sound of the coffee machine

• The heat from Benjamin's hot cup of coffee

• The movement of Benjamin pouring the coffee

• The light from the kitchen's flashlight

Ava, Hannah, and Luna are studying for their physics exam. They are discussing the difference between series and parallel circuits. Can you help them understand the difference?

• In a series circuit, like a string of Christmas lights, the components are connected across each other, while in a parallel circuit, like the wiring in their house, the components are connected end-to-end.

• In a series circuit, like a chain of paperclips, the components are connected side by side, while in a parallel circuit, like the lanes on a highway, the components are connected one after the other.

• In a series circuit, like a line of dominoes, the components are connected end-to-end, while in a parallel circuit, like the rungs on a ladder, the components are connected across each other.

• In a series circuit, like a disconnected necklace, the components are not connected, while in a parallel circuit, like a train on its tracks, the components are connected end-to-end.

Isla, Lily, and Ava are playing with a flashlight in a dark room. They notice that when they shine the flashlight on a mirror, the light beam bounces off. How does the light reflect off the mirror, which is a smooth surface?

• It reflects at a 90-degree angle

• It reflects at a random angle

• It reflects at the same angle it hits the surface.

• It absorbs the light completely

Aiden, Samuel, and Michael are experimenting with a laser pointer and a glass of water. They notice that the laser light changes direction when it hits the water. What is this process called?

• Reflection

• Refraction

• Diffraction

• Absorption
